NAME
     dr, drmach, ngdr, ngdrmach - Sun Enterprise  10000   dynamic
     reconfiguration driver

SYNOPSIS
     dr


     drmach


     ngdr


     ngdrmach


DESCRIPTION
     The  dynamic  reconfiguration  (DR)  driver  consists  of  a
     platform-independent  driver and a platform-specific module.
     The DR driver uses standard features of the Solaris  operat-
     ing  environment  whenever possible to control DR operations
     and calls the platform specific module  as  needed.  The  DR
     driver  creates minor nodes in the file system that serve as
     attachment points for DR operations.


     The DR driver provides a pseudo-driver interface to sequence
     attach  and  detach  operations  on system boards using file
     system entry points referred to as "attachment points."  The
     attachment point form depends on the platform.

  Sun Enterprise 10000 Server
     On the Sun Enterprise 10000 server, the DR  driver  consists
     of  a  platform-independent  driver  (ngdr)  and a platform-
     specific module (ngdrmach).


     The domain configuration server (DCS)  accepts  DR  requests
     from  the  system  services  processor  (SSP)  and  uses the
     libcfgadm(3LIB) interface  to  initiate  the  DR  operation.
     After  the  operation is performed, the results are returned
     to the SSP. For more information about the DCS  on  the  Sun
     Enterprise  10000, refer to the dcs(1M) man page and the Sun
     Enterprise 10000 Dynamic Reconfiguration User Guide.


     The DR driver creates physical attachment points for  system
     board slots that takes the following form:

       /devices/pseudo/ngdr@0:SBx

     Where x represents the slot number (0 to 15) for a  particu-
     lar board.


     The cfgadm_sbd(1M) plugin creates dynamic attachment  points
     that  refer  to components on system boards, including CPUs,
     memory, or I/O devices. Refer to the cfgadm_sbd(1M) man page
     for more details.
